DFI has performed a miraculous change of marketing directions in the past two years. They have moved from a solid second tier motherboard manufacturer producing nice OEM motherboards and a few solid, but dull, branded motherboards to a company whose products have come to define the Computer Enthusiast market. We can all chuckle when we say that Diamond Flower International became Designed For Innovation to fit their new image, but the transition is truly that remarkable.

A quick visit to www.xtremesystems.org or any other site devoted to enthusiasts who live to top the orb at Futuremark will find huge discussions of each little feature of upcoming DFI motherboards. Now, enthusiasts seem to ask with each new motherboard review, "That's fine, but what will the coming DFI do?" The DFI Socket 754 nF3 250Gb was one of the last 754 boards to market, but it was so heavily anticipated that DFI pre-sales totaled several months of production even before the board landed on the market.

This time around, the new nForce4 boards from DFI are some of the first to market, surely a first for DFI, and the new boards have already created quite a buzz when it was found that their new nF4 Ultra board, with two x16 PCIe slots, could be modded easily into an nForce4 SLI by closing a bridge on the nF4 Ultra chipset. Suddenly, a $140 motherboard could deliver everything that a full SLI board could deliver with a simple mod using a #2 pencil. Details of that mod are at Morphing nForce4 Ultra into nForce4 SLI. Add to that the incredible range of tweaking controls, which are becoming trademark DFI, and enthusiasts have been lining up to buy the new DFI nForce4 boards, which should actually be available right now.

There are two new DFI nForce4 boards covered in this review - the full-blown LANParty nF4 SLI-DR and the LANParty UT nF4 Ultra-D. However, the boards are basically the same and built on the same PCB. The LANParty is based on the nVidia nForce4 SLI chipset, while the UT has a few less features and is based on the nForce4 Ultra chipset. However, both boards sport 2 x16 PCIe slots, both boards perform the same, and they even use the same BIOS. As we found in the Ultra to SLI mod article, the UT board becomes, in every way, an SLI board after the simple mod. We will talk about the few differences between the boards in this review, but all benchmarking, overclocking, and memory performance tests apply equally to both boards.

DFI wanted to be certain that buyers of the lower-priced UT Ultra board still had all the overclocking controls and options available on the full-blown LANParty, and in this case, it is not just lip service. The SLI and Ultra boards can be considered equal in performance. The full-blown LANParty package with SLI adds a few more features to justify the $60 premium that the LANParty SLI will ask.

UPDATE 2/05/2005: nVidia has acted to prevent, or at least make it more difficult, to mod the Ultra board to SLI. First, DFI has advised us, and posted on their website, that they will NOT sell the SLI bridge to buyers of the Ultra board. Second, nVidia has advised us that future shipments of the Ultra chipset have been modified so that the mod to SLI will no longer be possible. An additional side effect of this second action is that the "Dual Video" mode, which performs at about 90% of SLI performance levels, will only work with nVidia SLI drivers 66.75 or earlier. If you do a quick check of web driver postings you will see it is now very difficult to find 66.75 drivers. With a chipset modded to SLI the "Dual Video" mode worked through 70.xx versions of the nVidia driver. nVidia also made it clear they will continue to make driver changes to prevent functioning of any "non-standard" (8X/8X) operation of their SLI driver. This also throws into question whether the VIA "dual graphics" mode on the 894 Pro chipset will ever work with nVidia graphics cards. If you are interested in the current UT Ultra-D we suggest you buy one now if you can find it. Future versions of the UT Ultra-D will not have the same capabilities as a result of these actions.

    Is there already performance benchmarks for ATI's SLI option?? -- it would hardly be surprising that it beats nvidia's solution as it is 6months if not a year after (I did read that they were using differing approaches to SLI) -- I was only stressing that if ATI were in the same position nvidia is in now, they would do the same thing of price gouging, stopping such easy mods etc...
    when ATI's solution comes out nvidia will respond with either lowering their price below ATI or developing their own next gen product -- and the cycle will continue || LATEST = GREATEST - usually :)

    They probably wouldn't have bothered if there wasn't so much press about it.

    It's only a few tens of dollars difference between an Ultra and official SLI board, given how much you'd be spending on two high-end graphics-cards if you go SLI, why would you even risk saving a few dollars in the first place and sourcing the bridge afterwards?

    The only people who are probably bothered about the Ultra to SLI mod being disabled, are those would would never buy two 6800GTs (or better) anyway. Reviews elsewhere have shown a 6800GT outperforms the 6600GT SLI in almost every game, so using SLI for 6600GTs is stupid.

    DFI would be fools to allow the Ultra to SLI hack to be continued if as a second-tier mobo manufacturer they expect to continue nVidia supplying them with chipsets. Even considering selling the bridge to Ultra owners struck me as foolish in the extreme for them.

    Myself I'll probably get an SLI board even though I'll never use two graphics cards, just because the price difference is so small compared with the other components that go into the system, and a mobo with all the bells and whistles is always nice to have "just in case".

    nVidia have made a great chipset in the nForce4, le's not deprive them of the revenue they deserve by not buying SLI boards if that's what you intend to do, or getting a lower cost board if you don't. Everyone who knows they'll never want to use SLI benefits from the price differential which allows Ultra chipsets to be sold slightly cheaper.

    word on the street is buy your ultra board before 2/20 if you want to use Wes' SLI discovery...still does'nt help you find a bridge..

    xsilver- Bullheads about to beat NF4 like a drum, hold your tounge. I don't blame nvidia but I also belive in the FREEDOM of mobo makers to do what they will with a chipset they purchased...not to be lorded over by nivida on the back end.

    Well, that update freaked me out. Ultra-D on order. ZZF seems to be the cheapest that's in stock. I'm still hoping to be able to play my vids in a surround gaming mode 3840x1024. We'll hafta see. Reply

    It's a disappointment that Nvidia has decided to making modding these boards harder but hardly a surprise. If anything it's surprising they didn't do this earlier. Reply

    Competition from ATI is the only answer to this price gouge. Do you remember back before AMD's Athlon when it was just Intel with AMD and Cyrix trailing far behind? Reply
  • xsilver - Saturday, February 5, 2005 - link

    lol -- bullhead will also be bullshit if ATI were in the same position -- nvidia is losing $30 per modded chip -- they want to reduce the possibilities of this --- duh! -- other mods were not 100% guaranteed - eg. opening pipes etc. but this was -- Reply

    The more I deal with nvidia scum (PVP on my $450 card anyone?) the more I think I'm waiting for bullhead (ati's chipset).. Reply
